SECARB Oil and Gas Formations The Southeast Regional Carbon Sequestration Partnership (SECARB) region, particularly Louisiana and eastern Texas, is an area with a rich history of oil and gas production. As such, considerable information exists on the geological settings and reservoir properties of these potential CO2 storage sites. The region has produced nearly 44 billion barrels of oil and nearly 332 trillion cubic feet of natural gas. Application of CO2 enhanced oil recovery (CO2-EOR) could add 13 billion barrels of oil to these totals. These oil and gas reservoirs provide opportunities for storing CO2, assuming that the water and low pressure gas occupying this pore space can be efficiently displaced with injected CO2. The CO2 storage capacity offered by the oil and gas fields in the SECARB region is nearly 31 billion metric tons. These oil and gas fields (see field location map on the opposite page) can provide excellent sites for securely storing CO2, given the presence of a porous and permeable reservoir overlain by a competent caprock. In addition, the SECARB region offers the potential for integrated application of CO2-EOR and CO2 sequestration, helping accelerate the storage of CO2 in the region.
